System has installed far away (in China) and there is bad Internet connection, so I might have ability to connect and check log files in a few day or weeks. Now I know exactly only that NUTed hosts shutdown via NUT as expected and no one host listed in shutdown-all-hosts.sh script don't. > >> Also I read somewhere that it is not a good idea to shutdown other hosts >> from the CMDSCRIPT. > >The User Manual chapter 7.2: > ><< It’s not a good idea to call your system’s shutdown routine directly >from the CMDSCRIPT, since there’s no synchronization with the slave >systems hooked to the same UPS.

Do you mean getting feedback to CMDSCRIPT about the "no NUTed" slaves indeed shutting down and/or some timing in NUT config files...? > >Roger >_______________________________________________ >Nut-upsuser mailing list >Nut-upsuser@lists.alioth.debian.org >http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
